README has wrong version

[omidbachari]

FYI
Readme says:

def deps do
  [{:coherence, "~> 0.6"}]
end

However, in https://hex.pm/packages/coherence it only has version 0.5.2. Users get this error:

➜  path-to-project git:(master) ✗ mix deps.get
** (Mix) No matching version for coherence ~> 0.6 (from: mix.exs) in registry

The latest version is: 0.5.2

See screenshot. Thank you!
